Article: How do people traditionally manufacture   things? They usually start with a sheet of metal, wood or other material and cut, drill   and shave it to create a desired shape. Sometimes, they use a mold   made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part. Now, a completely different method is gaining popularity. On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes  , toy dolls and even human organs - basically any product you can think of, reported Live Science. You might find it hard to believe that an object can actually be "printed out" like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays   ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3-D printer uses are mainly plastic, resin   and certain metals. The thinner each layer is - from a millimeter to less than the width of a hair - the smoother and finer the object will be. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward. For example, 10 years ago a desktop 3-D printer might have cost PS20,000 (200,000 yuan), while now it costs only about PS1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn't been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers. However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy  . "Once you can download a coffee maker, or print out a new set of kitchen utensils   on your personal 3-D printer, who will visit a retail   store again?" an expert on 3-D printing told Forbes News. Even more frightening, the world's first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons. 
 Question: According to the article, in the future, 3-D printing technology will probably   _  . 
 Options: (A) change the way people make products (B) be applied as widely in our daily lives as computers (C) forbid many countries to make purchases of weapons (D) take the place of normal printers and save lots of energy 
 Asnwer: A
answer:
Yes


question:
Article: Most people think that the capital of the movie world is Hollyhood, in the United States. However, the real movie capital is Mumbai, in India. Mumbai used to be known as Bombay, and so the film industry there is called "Bollywood." Bollywood makes twice as many movies each year as Hollyhood--more than 800 films a year. The movies from Bollywood are very different from Hollywood movies. For one thing, Bollywood movies are much longer than most Hollywood movies. Most Bollywood movies are more than three hours long, and contain singing, dancing, action, adventure, mystery, and romance (but usually no kissing). Because Bollywood films contain so many different features, this style of film is sometimes called a "masala" film. ("Masala" is an Indian word for a mixture of spices.) Another big difference between Bollywood and Hollywood movies is the way movies are made. It takes much longer to make a movie in Hollywood than in Bollywood. In fact, filming may begin on a Bollywood movie before the script even finished. The director and writers can make up the story while the film is being made. Sometimes they will even write the script by hand instead of taking time to type it. Bollywood actors are very popular and some are in such high demand that they may work on several movies at the same time. They may even shoot scenes for several films on the same day using the same costumes and scenery. Since most Bollywood movies follow the same kind of story, shooting scenes for several films at the same time is not a big problem for actors or directors. This also helps keep the cost of Bollywood movies lower than the cost of Hollywood movies. The average Bollywood film, with a budget of only two million U.S. dollars, seems very cheap compared to the average budget of sixty million U.S. dollars for a Hollywood film--thirty times as much! 
 Question: What is the main topic of the reading? 
 Options: (A) famous stars in Bollywood (B) how Hollywood movies are made (C) the differences between two movie industries (D) the history of movie-making in India 
 Asnwer: C
answer:
Yes

Article: Put technology in the hands of someone like Elon Musk and it can send people into space, make a future of clean and renewable energy a reality, or build electric cars. Put in your hands, and it can help you achieve all sorts of things, from learning to code to learning a language. Educational apps are becoming increasingly popular as a supplement , and sometimes as an alternative  , to traditional education. Why? Well, for starters, it's extremely convenient to learn on a pocket-sized device that you already carry around with you at all times. The best apps are also highly interactive and adaptive, _ . But apps, just like textbooks and language lessons, are a medium through which a language can be studied. The way you use them will affect how successful you are. If you flick through a textbook and don't dare say a word in your language lessons, you'll make slow progress. The keen reader who repeats each exercise in the textbook and engages the teacher in the conversation will move ahead. So how do you ensure you get the most out of your app, and what should you consider before you install  one? Before that, a very quick introduction: I developed the following five points from my experience as both a language teacher and learner, and from working in startups in the field of language. I spent six years teaching in Germany and Spain as well as developing a video learning startup. However, I first came to language learning late. I started learning Spanish at 22, and was able to use Spanish and German freely by about 28. I've been using language apps for the last few years, and participated in two successful one-week challenges to go from zero to hero in Italian and French. If you're interested, you can see the French challenge here. So, just before downloading an app, here's what you should think about... 
 Question: We infer that Elon Musk is most probably   _  . 
 Options: (A) an app developer (B) a language teacher (C) a professor at college (D) an engineer and tech company owner 
 Asnwer: A
answer:

No
